Porsche Doppelkupplung
(PDK).
PDK is available as an option for
the new 911 Carrera GTS mod
els. Gear changes take place in
milliseconds, for vastly improved
acceleration and lower fuel con
sumption.
In total, PDK has seven gears at
its disposal. Gears 1 to 6 have a
sports ratio, with the top speed
being reached in 6th gear. The
7th gear has a long ratio and
Six-speed manual gearbox.
Accurate and involving: the six
speed manual gearbox is the
link to each and every gear.
The cable operated gearshif t
unit is designed for optimum
progression through the gears
and the gear lever is insulated
from the engine and gearbox.
With minimal resistance, the
gear lever throw is short and
precise, enabling a rapid gear
shif t action and positive
response. helps to reduce fuel consump
tion even further. PDK is essen
tially t wo half gearboxes in one
and thus requires t wo clutches –
designed here as a double wet
clutch transmission.
This double clutch provides an
alternating, non positive connec
tion bet ween the t wo half gear
boxes and the engine by means
of t wo separate input shaf ts (input shaf t 1 is nested inside
the hollowed
out input shaf t 2).
The flow of power from the
engine is only ever transmit ted
through one half gearbox and
one clutch at a time, while the
next gear is preselected in the
second half gearbox. During
a gear change, therefore, a
conventional shift no longer
takes place. Instead, one clutch
simply opens and the other
closes at the same time. PDK and the manual gearbox
deliver power directly to the
road. With the optional Sport
Chrono Package Plus (p. 26),
you can make it even more
direct, and even sportier. With a
rush of adrenaline and euphoria,
you are straight into the action.
Precise actions hit the mark sooner.
The same is true of our transmission concepts.

Key features include a digital
and analogue stopwatch, the
SPORT button, a performance
display, a personal memory
function in the Porsche Commu
nication Management (PCM),
and – in combination with
Porsche Doppelkupplung (PDK) –
the SPORT PLUS but ton, and an For maximum dexterit y, PSM
can be set to standby while
the car is still in ‘Sport ’ mode.
For safety, it is set to intervene
automatically only when ABS
assistance is required on both
of the front wheels.
In combination with PDK, the
Sport Chrono Package Plus has
two additional functions that
are activated by pressing the
SPORT PLUS button, for a
sport y drive that borders on
a motorsport experience.
The first function is ‘Launch
Control’ which, for example
when performing laps, helps you
achieve optimum acceleration
from a standing start – a racing
start in other words.

Sport Chrono Package Plus is
available as an option. It of fers
even sportier tuning of the
engine and chassis, and delivers
even greater driving pleasure as
a result.
A harder rev limiter is also
applied in the automatic mode
of the optional PDK, while the
gearshif t points are delayed
until the upper rev range. The
shif t times are shorter, the gear
changes sportier. Even at low
rates of deceleration and at high
revs, the system initiates a swift
er, brake induced downshift.
In manual mode, gear changes
are faster and more dynamic.
In ‘Sport ’ mode, the trigger
threshold for PSM is raised for
increased longitudinal and later
al dynamics. Agilit y is enhanced
when braking for corners with
PSM enabling greater manoeu
vrability under braking and exit

speeds. The result? Increased
driving pleasure.
additional display in the steering
wheel which informs the driver if
the SPORT but tons and Launch
Control have been activated.
When the SPORT PLUS but ton
on the centre console is select

management system adapts for The function works like this:
press the SPORT PLUS but ton
when the transmission is in
‘D’ or ‘M’. Then, with your lef t
foot, press the brake pedal
and accelerate fully with the
right foot. The car recognises
‘Launch’ mode from the accel
erator kickdown action and
adjusts the engine speed to the
optimum level, which is around
6,500 rpm. At the same time,
engine torque is increased
and the clutch is applied lightly.

response to pedal input, a more
dynamic throt tle map opens the
throt tle valve wider than would
be the case in Normal mode.
The throttle response is signifi
cantly more immediate and a
harder rev limiter is also applied
in the higher gears. The second function is the
‘motorsport
derived gearshif t
strategy’. Using this, Porsche
Doppelkupplung (PDK) is geared
up for extremely short shif t
times and optimum shift points
for the maximum acceleration
available to the 911 Carrera GTS.
This combination of uncompro
mising and involving perform
ance is ideal for the racetrack.
Another key component of the
Sport Chrono Package Plus is
the stopwatch mounted on the
dashboard. Porsche Communi
cation Management (PCM) has
a special performance display
to view, store and evaluate lap
times or other driving times.
It shows the total driving time,
lap distance, lap number and
lap times recorded so far. You
can view the current fastest lap
Also influenced by ‘Sport’
mode is the standard equipped
Porsche Active Suspension

be recorded and benchmark
times defined.
The personal memor y function
of the Sport Chrono Package
Plus can also be used to store
personalised set tings for a
range of systems, including the
orientation lighting or air condi
